[0020] Please see Figures 1 to 3This utility model provides an embodiment of a highly versatile positioning device, comprising a base 10 and a pair of clamping blocks 1. The base 10 has mounting grooves 2 on both sides that match the shape of the clamping blocks 1. The two clamping blocks 1 are respectively embedded in the mounting grooves 2 on their corresponding sides. Each clamping block 1 has several positioning protrusions 3. The base 10 also has multiple adjusting countersunk holes 4. The adjusting countersunk holes 4 on the same side are connected to the mounting grooves 2 on the same side. The positioning protrusions 3 extend laterally into the corresponding adjusting countersunk holes 4. The positioning protrusions 3 and the adjusting countersunk holes 4 correspond to each other in number and position. The base 10 contains... The device has a transverse through-hole 11, within which a rotatable double-ended screw 5 is installed. The clamping block 1 has threaded holes 6 that are adapted to the double-ended screw 5. The two ends of the double-ended screw 5 are threadedly connected to the two threaded holes 6 respectively. When the double-ended screw 5 rotates relative to the threaded holes 6 of the clamping block 1, the clamping block 1 slides inward or outward along the mounting groove 2, adjusting the distance between the positioning protrusion 3 and the inner wall of the adjusting countersunk hole 4. This distance is the diameter of the clamped product, achieving the clamping effect. The adjustable distance between the positioning protrusion 3 and the inner wall of the adjusting countersunk hole 4 allows for the clamping of products of various sizes, improving versatility.

[0021] The clamping block 1 is provided with guide holes 7, and each guide hole 7 is provided with a limit screw 8. The inner side of the mounting groove 2 is provided with a limit screw hole 9 that matches the limit screw 8. After the limit screw 8 passes through the guide hole 7, it is threadedly connected to the limit screw hole 9. This structure is used to limit the movement of the clamping block 1 and protect the base 10.

[0022] The double-ended screw 5 has an annular arc groove 12 in the middle, and the base 10 has two insertion holes 13. Each insertion hole 13 is fitted with a limiting post 14. The two limiting posts 14 abut against the two sides of the annular arc groove 12 respectively. The two limiting posts 14 limit the double-ended screw 5 in the middle position of the product, so that it does not fall out of the base 10, and the double-ended screw 5 can rotate in the channel 11.

[0023] The double-ended screw 5 has adjustment countersunk holes 15 at both ends. In this embodiment, the adjustment countersunk holes 15 are hexagonal countersunk holes, and the double-ended screw 5 can be rotated by a hexagonal screwdriver. In this embodiment, the threads at both ends of the double-ended screw 5 are spirals in opposite directions. When the double-ended screw 5 is rotated, the two clamping blocks 1 perform synchronous opposite or opposite transmission.

[0024] The end of the double-ended screw 5 is also fitted with a sealing ring 16. The outer side of the clamping block 1 is covered with a cover plate 17. The sealing ring 16 abuts against the inner wall of the cover plate 17. The cover plate 17 is also provided with a round hole 18 corresponding to the position of the adjusting countersunk hole 15. The cover plate 17 can cooperate with the sealing ring 16 to cover the hole on the clamping block 1, thereby achieving a dustproof effect and improving service life. In addition, the sealing ring 16 can reduce the friction between the double-ended screw 5 and the cover plate 17, and at the same time play a buffering role, improving the service life of the device.

[0025] In this embodiment, the clamping blocks 1 are all convex in shape, wherein the positioning protrusions 3 are located at the sharp corners of the clamping blocks 1, and the positioning protrusions 3 are provided with inclined top surfaces 18, which can be adapted to cylindrical parts to make their clamping effect better.

[0026] The base 10 is disc-shaped and has several evenly arranged mounting holes 19. The positioning device can be fixedly installed on the worktable through the multiple mounting holes 19.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
